The Korean War was the first war in which jet aircraft played a central role. Once-formidable fighters such as the F4U Corsair relinquished their air superiority roles to a new generation of faster jet fighters. Within these pages are listed more than 1,140 U.S. Navy, U.S. Marine Corps and Military Air Transport Service (MATS) aircraft lost during the Korean War. These aircraft were spread across 19 different ships, 126 different squadrons, by 12 aircraft manufacturers building nearly 60 different types and variants to fly into war. The information on dates lost, aircraft type and manufacturer, Bureau Numbers, ship or base assigned, squadron attached, and fate of the pilot and crew, are here. Chapter 1 is a subset of all the information organized by ship attached; Chapter 2 is a subset organized by squadron attached; Chapter 3 is the entire set organized by manufacturer and variant with stories attached to some of the specific aircraft lost.
